USITC INSTITUTES SECTION 337 INVESTIGATION
ON CERTAIN DIGITAL MODELS, DIGITAL DATA, AND TREATMENT PLANS
FOR USE IN MAKING INCREMENTAL DENTAL POSITIONING ADJUSTMENT APPLIANCES,
THE APPLIANCES MADE THEREFROM, AND METHODS OF MAKING THE SAME

The U.S. International Trade Commission (USITC) has voted to institute an investigation of
certain digital models, digital data, and treatment plans for use in making incremental dental
positioning adjustment appliances, the appliances made therefrom, and methods of making the
same. The products at issue in this investigation are incremental dental positioning adjustment
appliances, or orthodontic aligners, and the digital models, digital data, and treatment plans used
to manufacture those appliances.

The investigation is based on a complaint filed by Align Technology, Inc., of San Jose, CA, on
March 1, 2012. The complaint alleges violations of section 337 of the Tariff Act of 1930 in the
importation into the United States and sale of certain digital models, digital data, and treatment
plans for use in making incremental dental positioning adjustment appliances, the appliances
made therefrom, and methods of making the same that infringe patents asserted by Align
Technology. The complainant requests that the USITC issue cease and desist orders.

The USITC has identified the following as respondents in this investigation:

By instituting this investigation (337-TA-833), the USITC has not yet made any decision on the
merits of the case. The USITC's Chief Administrative Law Judge will assign the case to one of
the USITC's six administrative law judges (ALJ), who will schedule and hold an evidentiary
hearing. The ALJ will make an initial determination as to whether there is a violation of section
337; that initial determination is subject to review by the Commission.

The USITC will make a final determination in the investigation at the earliest practicable time.
Within 45 days after institution of the investigation, the USITC will set a target date for
completing the investigation. USITC remedial orders in section 337 cases are effective when
issued and become final 60 days after issuance unless disapproved for policy reasons by the U.S.
Trade Representative within that 60-day period.
